Bioacoustics of Salomona manobo

Description. Male habitus as shown in Figs 5 , 6A, 6B . Fastigium verticis in dorsal view elongated conical, apex subacute, about as long as scapus, with ocellus in middle ( Fig. 6C ). Vertex subrugose ( Fig. 6C ). Frons with large impressed dots, genae rugose ( Fig. 6D ). Pronotum subrugose with small impressed dots and wrinkles, disc broadly rounded into paranota, apical area subflat and shouldered ( Fig. 6E ); anterior margin straight; posterior margin broadly rounded ( Fig. 6C ). Acoustic spiracle completely covered by paranota ( Fig. 6E ). Tegmen macropterous, slightly surpassing abdominal apex and just as long as hind wing, apex obliquely rounded ( Figs 5 , 6A, 6B ). Prosternum with two stout spines with obtuse apices ( Fig. 6F ). Mesosternal and metasternal lobes conical with blunt apices ( Fig. 6F ). Femora with the following number of robust spines on ventral margins: anterior femur 9 external, 7 internal of increasing size distally; middle femur 6 external of increasing size distally, 3 internal at base; posterior femur 9 external of increasing size distally, 0 internal. Knee lobes of anterior and middle femora obtuse externally and long spinose internally; of posterior femur spinose on both sides. Tibiae with the following number of spines on ventral margins: anterior tibia 5 external, 4 internal; middle tibia 7 external, 3 internal. Male. Mirror on left tegmen pentagonal, 1A mostly straight ( Fig. 7A ). Stridulatory file on underside of left tegmen straight; about 2.9 mm long; with teeth increasingly wider and more widely spaced towards middle (compared to basal end); with circa 75 teeth ( Fig. 7B ). Mirror on right tegmen more roundish ( Fig. 7C ). Tenth abdominal tergite with its posterior margin very broadly and roundly emarginated and having lateral lobes at lateral ends; lateral lobe triangular with apex rounded ( Figs 7D, 7E ). Epiproct in posterior view tongue-shaped and at basal half slightly depressed at middle ( Fig. 7D ); in dorsal view rectangular with posterior margin emarginated and forming two lateral rounded lobes ( Fig. 7E ). Cercus mostly cylindrical and slightly curved internally; at apical third along inner margin with finger-like internal process; internal process small, bulbous, rounded apex; apex of cercus curved slightly inwards, bluntly triangular ( Figs 7D–H ). Subgenital plate about as long as wide, lateral margins slightly converging towards apex; with posterior margin deeply and roundly excised and having stout styli ( Fig. 7H ). Titillators separate ( Fig. 8 ); bases curved slightly laterad, otherwise simply long-lamellar; apical extensions, in lateral view, expand apically and somewhat reniform; dorsal margin with numerous spines of different sizes and irregularly spaced apart. Female. Unknown.
